Asriel could only watch in horror and delight as Toriel’s teeth dug into his body, ripping into his flesh. However, he feels no pain, as he’s just a living cookie version of his former self. This cookie shell does have his soul inside it, as the real one is sound asleep. To him, it’s just a dream he will wake up from and forget, but she won’t.
 
He watches as his lower half, sliced off with a knife, slowly slips into her mouth. He can feel her tongue working around it as her teeth slowly chew it into pieces and mush. She watches the wiggling top half with delight. She has no connection to this confectionery creation aside from loving the feeling of it’s wiggles. She will swallow the top half whole, letting it wiggle around as it’s turned into fat for her. Her one regret is that the real one won’t remember.
